3. (a) Estimate the fractional change in the volume of Earth's oceans due to an average temperature change of 1°C.
(b) Use the fact that the average depth of the ocean is 4.00x10^3 m to estimate the change in depth. Note that βwater=2.07x10^-4 (°C) ^-1.
Suppose the incident sunlight at ground level has a power density of 0.87 kW m−2 at noon. What is the maximum rate of loss of water from a lake of area 1.0 ha? (1 ha = 104 m2.) Assume that all the radiant energy is absorbed; take the enthalpy of vaporization of water to be 44 kJ mol−1.
Given these two equations, calculate Cv for CO2 and N2 using the velocity of sound.
6. According to statistical mechanics, the contribution to Cy due to the ith vibrational
mode of a molecule is

where Oi = hcv./kB, h is Planck's constant, and c is the speed of light in cm s-¹. v; is the
vibrational frequency of the ith vibrational mode in wavenumbers (cm-¹). The quantity
O, has dimensions of temperature and is sometimes referred to as the vibrational tem-
perature (of the ith vibrational mode). The total vibrational contribution to the molar

Calculate Cy for CO₂ at 300 K, assuming that the translational and rotational con-
tributions are (3/2)R and R, respectively, and use the preceding equations to obtain the
vibrational contribution. Four vibrational modes for CO₂ are expected (3N- 5). How-
ever, three fundamental frequencies are observed at v= 667.3, 1340, and 2349.3 cm-¹.…
